Hello, Have a look at this page of the eBook: http://www.allaboutcircuits.com/textbook/digital/chpt-7/boolean-rules-for-simplification/ Bertus
Thanks I've gone through it couple of time but it doesn't cover some of these "awkward" derivatives of the rules.
Hello, It only works in the case : A + AB You are right, in your shown case B and B' are not the same so it does not work. Bertus
Hello, Yes, as (1 + B) give a 1 as result, but (1 + B') also gives a 1 as result. A 1 orred with any value will give a 1 as result. Bertus
